George, not sure which fuse you checked. Check fuse number #60 in the multi fuse relay box (located on the left front of the engine compartment) It is a 40Amp fuse. Also check fuse #3 on the driver's side underdash fuse box. It is a 7.5 Amp fuse that goes to your Rear heater A/C mode control motor. It is on the back side of the rear blower unit. If you get power to the rear blower motor, check the blower resistor, which is attached on the rear of the blower unit.
